To all whom it may concern:

Be it known that I, CHARLEs E. SMITH, a resident of Oak Lawn, in the town of Cranston, State of Rhode Island, have invented a new and useful Improvement in Machines for Packaging Metallic Leaf in Rolls, of which the following is a specification.

My invention consists in the improved construction of the machine whereby an 1ncreased degree of pressure is applied to the rear end of the sheet of metallic leaf as it is being fed to the supporting strip, so that the rear end of the said sheet will be prevented from dropping away from the surface of the supporting paper strip upon the downward movement of the traveling bed by means of which the sheets of metallic leaf are applied to the strip.

It also consists in the employment of a rotary scratch brush for abrading the surface fibers at one side of the supporting strip preparatory to the reception thereon of the sheets of metallic leaf.

In the accompanying drawings: Figure 1 represents a side elevation of the machine. Fig. 2 represents a detail view taken from the front of the machine. Fig. 3 represents a side elevation taken at the side opposite to that of Fig. 1. Fig. 4 represents a top View of the traveling bed and the book-supporting table. Fig. 5 represents an edge view of the same. Fig. 6 represents a section taken in the line 6, 6, of Fig. 4. Fig. 7 represents a section taken in the line 7, 7 of Fig. 4. Fig. 8 represents a vertical section showing the traveling bed in its rearward tilted position. Fig. 9 represents a plan view of the pivotally held track member. Fig. 10 represents the forward end view of the same. Fig. 11 represents a vertical section showing the traveling bed when raised to the under surface of the pressure roll for lapping the metallic leaf upon thesupporting strip. Fig. 12 represents a section taken in the line 12, 12 of Fig. 2. Fig. 13 represents a vertical section showing the traveling bed at or near its forward position.

In the drawings, A and B represent the side frames of the machine, and C the bed plate to which the side frames are attached. The machine is operated from a pedal attached to rod Y by means of the vertically sliding rack D, which is supported in the brackets a, a, atthe outer side of the s1de frame B. The gear E, which engages with the rack D,

is loosely held upon a stud b, which projects from the side of the frame B, and the said gear engages with the pinion F which is tight upon the shaft G, of the pressure roll H of the machine; and to the shaft G, between the side frames A and B, is secured the gear I, the teeth of which engage with the teeth of the horizontal sliding rack J, held for movement in the guide brackets K, K, which are secured to the frame B as shown in Fig. 2, the said rack being provided at its lower side with the notch or recess a, which is adapted for loosely holding the projection 12 which extends laterally from the traveling bed L as shown in Figs. 4 and 7, so that the traveling bed will partake of the movement of the rack J, and at the same time be adapted for receiving a tilting movement at its extreme rearward position, the said rack J being always in engagement with the teeth of a gear I, splined t0 the shaft G, which latter is journaled in the frame members A and B, as shown in the detail section Fig. 2, and at the inner side of the gear I, are placed the pivoted spring actuated dogs 0, 0, which engage with the lugs (Z, (Z, formed upon the outer side of the gear W, the said gear being secured to the side of the said pressure roll H, which forms a supporting bed for the strip of paper 6 upon which the metallic leaf is to be placed; the said gear IV and pressure roll H being loose upon the said shaft G. The pitch line of the gear W, conforms to the periphery of the said pressure roll, and the teeth of the said gear engage with the teeth of the gear X, which forms an intermediate between the gear W, and the gear Y, which latter gear serves to drive one of the rolls V of the winding up cluster. The package roll of metallic leaf A, is wound up as usual. in the space between the stationarily held roll V, the pressure roll H, and the spring actuated movable roll Z. The rotary scratch brush B, formed of wire, is driven from the gear IV, by means of the gear C upon the shaft f of the said scratch brush, and the intermediate gear D, and by means of the said scratch brush the surface fibers of the paper strip 0 are abraded at one side to facilitate the attachment of the metallic leaf thereto. The shaft f of the brush B is held by the arms 9, g, which are secured to the pivot rod E, journaled in the side frames A and B. Crocus,

rotten stone or other powdered material is applied to the roll h of the paper strip 6, from the hopper K shown in Fig. 4, and evenly spread over the surface of the unwinding paper strip by means of the weighted pad 2', the said paper strip passing thence under the bar j, then over the surface of the pivot rod E to contact with the scratch brush B, and onto the periphery of the pressure roll H,'for the reception of the metallic leaf.

The traveling bed L, is arranged between the cheeks F, F, and fulcrumed upon the pivots of the swivel guides G, G, which are held in the longitudinal edge grooves H, H, the said traveling bed having its forward end tilted downward by the upward action of the spring actuated bolt I upon the under side of the said traveling bed beyond its turning fulcrum, as shown in Fig. 8. The said traveling bed is also provided at its upper side with the sliding bookreceiving table, J, upon which the gold beaters book of metallic leaf is to be placed, so that the said book may be moved back and forth by the operator independently of the movement of the traveling bed. The outer end of the traveling bed is to be pressed down by the operator, thus carrying the forward end of the said bed upward to bring the forward edge of the book which is placed upon the receiving table J into lapping contact with the previously applied sheet of metallic leaf, and then the machine is to be set in operation for causing the complete attachment of the sheet of metallic leaf to the supporting strip 6, whereupon the traveling bed and the book of metallic leaf located upon the sliding table J will be carried forward under the pressure roller H, with the lateral studs 6, b, of the traveling bed, resting upon the supporting tracks 2?, t, of the bifurcated track member W, the said member being pivoted to the side frames A and B, at the point a, and pressed upward at its outer end by means of the springs 'v, o, which press upward from the downwardly extending lugs w, w, of the cross tie-plate X of the frame. The said springs 12, 'v, are held upon the downwardly extending rods 6 ,6 which are jointed at c c to the track member W, the said rods passing loosely through perforations made in the said lugs to, 'w; and on the said rods 6 6 below the said lugs, are placed the spiral springs cl, d, which are the equivalents of the springs v, o, and to the lower ends of the rods 6 6 is secured the tie-bar e which serves to connect the said rods together; and to the middle portion of the said tie-bar e is secured the air cylinder f, which in conjunction with the piston 9, forms a dash-pot for checking the upward movement of the track member W when relieved from the weight of the table L, thus avoiding a sudden jar to the machine with accompanying loud noise, and this c011- nection of the spring-actuated track member TV, with a dash-pot, constitutes a desirable feature of my improvement. Now, upon the continued forward movement of the feeding table L, the lateral studs 6 b, of the traveling bed will fall over the ends w, :v, of the tracks 2?, t, and the said traveling bed will then be carried backward by the backward movement of the rack J, the forward end of the said traveling bed then resting upon the tracks y, 3 of the cross tie-plate X, until the said forward end reaches and passes beyond the ends of the said tracks and drops to a lower position at the end of the stroke of the rack J as shown in Fig. 1. The operator now draws back the sliding table J upon which the boo-k of metallic leaf is held, and after exposing a new sheet of metallic leaf carries it again forward by the forward movement of the said table upon the traveling bed, and then, by tilting the forward end of the traveling bed upward, causes the proper lapping of the edges of the sheets of metallic leaf upon each other. Now, upon starting the machine in operation, the metallic leaf will be deposited from the said book upon the surface of the supporting strip as before described. The bifurcated track member W being pivoted at the point U, and pressed upon at its outer end by means of the springs a, '0, serves to provide a gradually increasing leverage for pressing the traveling bed L upward as the said traveling bed moves forward toward the pivoting point U, of the said track member. And in addition to this, the blow exerted by the forwardly moving rack J upon the adjustable stop pin a, which is held in the upwardly extending lug a of the bifurcated track member W, and by means of which the momentum of the traveling bed is checked will serve to increase the closing pressure between the traveling bed L and the pressure roller to cause the firm connection of the rear end of the sheet of metallic leaf to the supporting strip, and prevent it from dropping away therefrom.

The spring 00 which serves to actuate the movable roll Z of the winding u mechanism, provides a gradually increaslng pressure upon the package roll, caused by the gradually increased compression of the said spring as the package roll is being wound, whereby the supporting strip and the metallic leaf may be wound with uniform tightness throughout the whole extent of the roll.

The fiat spring V which is fastened at one end to the tie-plate X serves to prevent the too sudden drop of the forward end of the table, when it passes from engagement with the inner ends of the tracks 2,, t, onto the lower tracks y, y, of the cross tie-plate.

I claim as my invention 1. In a machine for packaging metallic leaf in rolls the combination of a pressure roll, the traveling bed adapted for forward movement with the pressure roll, and a hand operated slidin table adapted for supporting the book of metallic leaf upon the traveling bed and for movement beyond the outward movement of the said traveling bed, to allow the operator to turn the leaves of the book for the repeated operation of the ma chine.

2. In a machine for packaging metallic leaf in rolls, the combination of means for abrading the surface of the supporting strip a mechanism for applying the sheet of metallic leaf to the abraded surface of the strip,

and means for winding up the abraded supporting strip and the attached metallic leaf into a package roll.

3. In a machine for packaging metallic leaf in rolls, the combination of a pressure roll, and the traveling bed with a pivoted spring-actuated track member for supporting the traveling bed and a dash-pot for checking the resilient upward movement of the said track member when freed from the traveling bed.
